2 Claims. (Cl. -5

The present invention relates to building and construction materials, generally classified, and has more particunited States Patent 50 lar reference to a simulated or imitation log which lends V itself to use as siding and which, like any other article of siding, may be aptly employed in building walls, partitions and similar structures.

It is a matter of common knowledge that so-called halflogs are extensively used in covering and enclosing frameworks, made up chiefly of studs and joists, in the course of constructing and building a house, cottage, barn, trailer body, etc. Inasmuch as the log cabinefiect is desirable in erecting structures for rustic appearance, persons engaged in this line of endeavor are constantly seeking to provide imitation logs to take the place of heavy and expensive solid logs. It follows that the art to which the invention relates reveals various styles and forms of composite logs which, for the most part, are hollow and, therefore, comparatively light in weight.

The object of the present invention is to structurally, functionally and otherwise improve upon hollow imitation and simulated building logs and, in so doing, to provide one in which manufacturers, builders and others will find their respective requirements and needs aptly and satisfactorily met.

In carrying out the principles of the present invention, a hollow simulated building log is formed and molded into semicircular shape and is characterized by two components or complements; one, a board which is especially designed in cross-section and which serves as a backing and foundational member, and the other, a semicircular sheath which provides the log finish and which may be, and preferably is, formed from substantially semi-circular laminations of plywood which are press-formed and glued and thus bonded together.

One phase of the concept has to do with the complete log made up of the components or units menu'oned above which are secured together and transported, as such, ready for constructional purposes. Another aspect of the invention has to do with the stated components or units which may be separately made, packaged and shipped unassembled or in knock-down form, transported for use separately in cartons in order that they may be assembled on the job without special tools or equipment.

Another object of the invention has to do with a building log which is light, compact, durable and attractive and involves the use of hard wood and yet is economical to all concerned and is susceptible of use as any other piece of siding over a conventional building or equivalent framework, said log being further desirable in that it offers the user desired insulation properties.

Briefly summarized, the invention has to do with an elongated board having a smooth flat side adapted to firmly contact and to be secured to studs in a supporting framework, the upper longitudinal edge thereof being transversely convex, the lower longitudinal edge thereof being transversely concave, the other side of said board having a lengthwise rabbet adjacent to said lower longitudinal edge and defining a shoulder and a relatively thin flange depending below said shoulder, said board providing 'a base or foundation for the complemental sheath unit which is, in effect, a semi-circular imitation log and whose upper longitudinal edge portion is adapted to overlap the upper longitudinal edge of the board and whose lower longitudinal edge portion is adapted to simultaneously abut said shoulder and the adjacent surface portions of the coopereating depending flange.

Other objects, features and advantages will become more readily apparent from the following description and the accompanying sheet of illustrative drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the same:

Figure l is a fragmentary perspective view showing what may be considered to be either the interior or exterior of a building or an equivalent wall having the aforementioned ornamental or rustic log cabin effect;

Figure 2 is an enlarged vertical section taken on the plane of the line 2-2 of Figure 1, looking in the direction of the arrows;

Figure 3 is a fragmentary perspective view of one of the imitation or simulated logs, observing one side of the same; and v Figure 4 is a similar perspective View of the same, observing the opposite side thereof.

Referring now to the drawings by way of reference numerals and accompanying lead lines, the numeral 6 in Figure 2 designates a vertical stud or similar support memher which may be treated as a part of a building Wall framework. The invention is, however, in the composite or improved log per se, and the description will proceed accordingly. As before stated, the composite log is made up of two units or components; namely, the solid longitudinally elongated board 8 and the complemental cover or sheath 10, and when the two units are assembled and fastened in themanner shown, they provide a hollow log with an insulating or air space, as at 12.

The board is of a suitable length so that its attachable smooth flat sides 14 may be placed against and nailed, or otherwise secured, to the studs 6. The opposite face is also flat, as at 16. The top longitudinal edge is convex in a transverse direction, as denoted at 18. The lower edge is concave, as at 20. The lower edge portion is rabbeted along the side 16 adjacent to the lower edge portion to provide a flange 22 and a shoulder 24 and to also define the simulated cement or equivalent mortar joint between the respective logs when they are in wall forming relation, as shown in Figure 2. As before explained, the unit 10 is preferably semi-circular in crosssection, or substantially so, and is composed or made up of a plurality of plies or laminations of plywood denoted by the numerals 26. These are properly formed and shaped in a press and are glued together and thus bonded into one unit. The upper longitudinal edge portion 28 overlaps and, is conformingly fitted upon and attached to the convex longitudinal edge 18 of the board. The lower longitudinal edge portion 30 is at a plane outwardly of the surface 14 and also of the margin 32,0f the upper edge where it is thus properly positioned or located to bear against the flange 22 and to abut the shoulder 24, this in a manner so that the lower half portion of the flange depends to a plane below said edge portion 30.

It will be seen that the invention, therefore, has to do with a building log which may .be assembled on the job and may be shipped knocked down or unassembled for compact packaging while in transit, may be applied over an open or skeleton framework for original construction work or may, if desired, be applied over old wall surfaces.

herein revealed ofiers great saving in material as comparedto solid members. It is light in weight, with selfcontained insulation space and standardized and uniform in over-all appearance. The semi-circular units or components-l0jmay be mounted without'the backing board 8 over-lumber or sealedwallskby using a mountingstrip or a suitable standard. In practice, semi-circular end caps (not shown). may be plugged into the ends of the air chamber 12 and properly used for joining the ends of two logs together.

From the foregoing, the construction and operation of the device will be readily understoodand further explanation is believed to be unnecessary. However, since numerous,jmodificationszand, changeswill readily occur to those skilled in the art, it is not, desired to limit the invention to the exact construction shown and described, and accordingly, allsuitable modifications and, equivalents may be resorted to, falling, within the scope of the appended claims.

What is claimed as new, is as follows:

1. A simulated log for building and construction work comprising a structural unit embodying an elongated board having a smooth flat side adapted to firmly contact and to be secured to studs in a framework or the like, the upper longitudinal edge thereof being transversely convex, the lower longitudinal edge thereof being transversely concave, the other side of said board being substantially flat and having'a lengthwise rabbeted groove adjacent said lower longitudinal edge and defining a longitudinally extending shoulder and a relatively thin flange depending to a plane below said-shoulder, and a complemental imitation log comprising a longitudinally elongated laminated sheet material substantially semi-circu' lar in cross-section, the upper'longitudinal edge thereof overlapping the convex longitudinal upper edge portion of said board for nailing and retention thereon, the lower longitudinal edge portion terminating in a plane spaced outwardly from the plane of the upper longitudinal edge portion and abutting an exterior surface of said shoulder and an adjacent surface portion of said flange, a portion of the flange depending therebelow and being thus completely exposed for nailing and providing an imitation joint between an adjacent complemental imitation log.

2. A new article'of manufacture comprising an elongated board having a smooth fiat inward surface adapted tofirmly contact framework studs for nailed attachment to said studs, said board being substantially rectangular in cross-section, the upper longitudinal edge of said board being transversely convex, the lower longitudinal edge of said board being transversely concave, the outward side of said board having a lengthwise rabbet adjacent to said lower longitudinal edge and defining a lengthwise shoulder and a flange of reduced thickness depending below 'said shoulder, and the combination with said board of a length of laminated sheet material transversely curved and formed into semi-circular shape and defining, in conjunction with the board, an imitationlog, the upper longitudinal edge of said sheet material overlapping the upper longitudinal edge of the board and being fastened References Cited inthe file of this patent UNITED STATES PATENTS 1,496,368 Cooper June 3, 1924 1,528,397 Brenner Mar. 3, 1925 1,953,460 Bernhard Apr. 3, 1934 2,038,250 Swanson Apr.2l, 1936 OTHER REFERENCES American Builder, of February 1933, page 33.
